Community and household socioeconomic factors associated with pesticide-using, small farm household members' health: a multi-level, longitudinal analysis por Cole, Donald C., Orozco, F.A., Ibrahim, S., Wanigaratne, S.

“…Community percent with unsatisfied basic needs was associated with reductions in 2007 digit span: -0.04(0.01) per percent for household and -0.03(0.01) for crop managers.The important roles of life endowments and/or persistent neurotoxicity were exemplified by limited change in the health outcome. Gradients by household assets and community deprivation were indicative of ongoing, structural inequities within this LMIC.…”

Breeding annual grain legumes for sustainable agriculture: New methods to approach complex traits and target new cultivar ideotypes por Duc, G., Agrama, H., Bao, S., Berger, J., Bourion, V., Ron, A.M. de, Gowda, C.L.L., Mikic, A., Millot, D., Singh, K.B., Tullu, A., Vandenberg, A., Vaz Patto, Maria C, Warkentin, T.D., Zong, X.

“…Although yield and total biomass produced by annual legumes remain major objectives for breeders, other issues such as environment-friendly, resource use efficiency including symbiotic performance, resilient production in the context of climate change, adaptation to sustainable cropping systems (reducing leaching, greenhouse gas emissions and pesticide residues), adaptation to diverse uses (seeds for feed, food, non-food, forage or green manure) and finally new ecological services such as pollinator protection, imply the need for definition of new ideotypes and development of innovative genotypes to enhance their commercialization. …”

Closing system-wide yield gaps to increase food production and mitigate GHGs among mixed crop–livestock smallholders in sub-Saharan Africa por Henderson, Benjamin B., Godde, Cécile M., Medina-Hidalgo, D., Wijk, Mark T. van, Silvestri, Silvia, Douxchamps, Sabine, Stephenson, E., Power, B., Rigolot, Cyrille, Cacho, O., Herrero, Mario

“…We also assess their potential to increase food production and reduce the GHG emission intensity of their products, as a result of closing these yield gaps.We use stochastic frontier analysis to construct separate production frontiers for each site, based on 2012 survey data prepared by the International Livestock Research Institute for the Climate Change, Agriculture and Food Security program. Instead of relying on theoretically optimal yields—a common approach in yield gap assessments—our yield gaps are based on observed differences in technical efficiency among farms within each site. …”

Long-term effects of TSP and Minjingu phosphate rock applications on yield response of maize and soybean in a humid tropical maize–legume cropping system por Savini, Isaac, Kihara, Job Maguta, Koala, Saidou, Mukalama, John, Waswa, Boaz Shaban, Bationo, B. André

“…This implies that adoption of either MPR or TSP by farmers in western Kenya is profitable for maize and soybeans production, given that MRRs were above 100 % minimum acceptable rate of return which is a requirement for farmers to change from one technology to another.…”

Nutrition challenges ahead por Chen, J., Fewtrell, M., Kennedy, G., Naska, A., Riediger, K., Roos, N., Sanders, T., Tuohy, K.M., Valtuena-Martinez, S.

“…At a global level, food security, food sustainability and decreasing the impact of food production on climate change are of paramount importance. Decreasing the prevalence of obesity and related disorders, which may coexist with selected micronutrient deficiencies, is a major challenge for wealthy countries; for developing countries and rural food systems, fighting protein–energy malnutrition and micronutrient deficiencies is a priority. …”

High-throughput phenotyping and improvements in breeding cassava for increased carotenoids in the roots por Belalcázar, John Eiver, Dufour, D.L., Andersson, Meike S., Pizarro, Mónica, Luna, Jorge, Londoño Hernandez, Luis Fernando, Morante, Nelson, Jaramillo Valencia, Angélica M., Pino, Lizbeth, Becerra López Lavelle, Luis Augusto, Davrieux, Fabrice, Talsma, Elise F., Ceballos, H.

“…It is postulated that variation in the environmental conditions when seedling and cloned plants (from the same genotype) may be responsible for these weak associations. Important changes in selection strategies have been implemented to overcome problems related to a lengthy harvesting season.…”
